Plugins

Plugins give you an ever increasing range of
capabilities, but allow you to choose only those
that fit your needs. No more excess baggage
to carry around and slow you down.

Four plugins are available. They provide 8
additional statistical analysis and visualization
methods. Previous releases of ViSta included
the functionality that is now available in the
core engine plus the multivariate and multidimensional
scaling plugins (but these plugins also provide
cluster analysis and nonmetric MDS, both not
previously available).

Homogeneity Analysis by Jan de Leeuw
(April 25th, 2001 - 773 KBytes download).
Jan de Leeuw's homogeneity analysis (Homals)
has been interfaced with ViSta. No visualizations
are available at this date. Unless there
are problems with the interface, this is a
mature and reliable system.

MultiLevel Modeling
(April 25th, 2001 - 767 KBytes download).
Multilevel modeling, with unique visualization
capabilities. This is a new module that interfaces
the Terrace package with ViSta. While
Terrace has been extensively used, the interface
and visualizations are new. Please let us
know of any problems.
